"Carrie and Big, meanwhile, endure barbed pity from other couples because of their decision to remain childless. 'You mean it's just the two of you?' a fellow guest at Stanford and Anthony's wedding asks, incredulous."

Carrie frowns and closes the laptop shut. She looks around for another distraction. She picks up a framed picture of Big on her desk and touches it lovingly.

Forgive the meta opening, but that was the question I got in my mind while reading the reviews of SATC 2, and it seemed like it would be great fodder for one of Carrie's old fictional columns. The paragraph I included above from the NYT review of the movie specifically jumped out at me when I read it.

"Wonderful though being a mother is on many levels, it also complicates your life in many ways, and that's the truth, just as it's also true that our culture tells us that a woman 'of a certain age' without a child is somehow incomplete and must be unhappy, even if she won't admit it," writes Voynar. "And SATC 2 does try to address this issue somewhat, by having everyone Carrie and Big encounter question their decision to remain a wealthy, childless couple (one pair at the wedding actually physically moves away from Carrie and Big when they say they don't want kids, as if the desire to remain childless is a disease that might be catching)."

It's not "catching," as in communicable, but the decision not to have kids is a movement that seems to be catching on and growing vocal on the Internet. It's called childfree by choice. The reasons why some couples choose not to have kids "are varied and complex," an ABC News piece on the topic points out. "Some have environmental, religious, medical or professional reasons. For others, it's a matter of happenstance — they didn't meet the right partner or the time just never seemed right."

REDBOOK profiled one such married couple in a past story called "The State of Our Unions." Rebecca Stephens, a pharmaceutical sales representative, and Jim Stephens, a psychotherapist, had been married for 12 years and always knew they didn't want children.

"When someone asks me if I have kids, I often feel almost apologetic when I say no, like I have to provide a 'good enough' reason or they'll take pity on me and assume I can't have children," said Rebecca. "But I just don't have the gene for wanting a child, and I don't think having a child would improve our relationship. I usually tell people that we've chosen to go the dog-and-cat route and leave it at that."

Rebecca went on to list what she likes about being a family of two. "Being the only people in this relationship, we are each other's first priority, emotionally and otherwise. We are more communicative and can lavish attention on each other — something we might not be able to do if we were always focused on baths and homework. We also like that we get to live a bit more whimsically without children. We can take bigger career risks — I had my own business for a while and Jim started his own practice two years ago. We travel a lot, and we go out even more than we did when we were single."

We also got a significant online response from childfree couples on our "How Many Kids Should You Have?" piece. Reader kirby78 commented: "I have been with my husband for 11 years. We are not child hating adults who complain at the sight of a baby, nor are we career driven yuppies. We are not self-absorbed, selfish, or immature. We are a normal, well-adjusted, happy couple who has decided to never have children. The reasons are varied and far too in-depth for a short comment here, but it would be nice to also address 'Families of two' who, whether by choice or circumstance, have decided that two adults *are* a family." Another reader, heather-ann, cited medical issues: "I was diagnosed with uterine cancer at the age of 29,and subsequently don't have any 'baby making bits' left. Dealing with the pain of being infertile and with adoption processes that were both insensitive and invasive, my husband and I have grappled over the years with the idea of our family being 'just us.' To yet again be presented with the idea that without children we are incomplete as a family seems somewhat unenlightened."

Just as kirby78 mentions some derogatory labels, the ABC News piece also highlights the name-calling that often happens to these couples as a result of their lifestyle: "They're told they are: Self-centered, deviant, workaholic, immature, and child-haters." The Wikipedia entry on "Childfree" even has a section labeled "The 'selfish' issue" explaining the debate and summarizing the positions and the responses from childfree groups. (One childfree by choice rebuttal breaks down the oft-cited reasons why people opt to have children and the oft-cited reasons why people choose not to procreate into two lists, and argues that the reasons why people have children could be deemed equally "selfish," since they include factors like feelings of personal satisfaction and improved social status that parents may gain for themselves.)

Back to Sex — is it a big deal that Carrie has never carried a child? Does it make the Prestons a selfish couple because, as Voynar puts it, they "have plenty of money with which to raise a child (or two, or three) but that they are staunchly devoted to remaining a childless couple, keeping all their time and money and spendy couches and designer clothes to themselves?"

Voynar gives her verdict: "In a way, sure...but isn't it better, if people know that they don't have the kind of energy and selflessness that being a parent requires, for them to be honest about this and not bring into the world a child whose presence would ultimately be resented just for the sake of fulfilling some societal mandate to reproduce?"

What do you think of the decision not to have children? Is it selfish? Or are couples who choose to be kid-free just self-aware enough to know that, for whatever reason, they're not parent material? Are you childfree by choice?
